This is pretty slick - at first the reader suspects that there's some kind of cognitohazard in play affecting the Foundation in-universe, and then the message at the end (which neatly manages to avoid being an explanatory note thanks to its in-universe context) provides a nice twist ending that completely recontextualizes the piece. A good example of crosslinking and hopefully a sign of things to come.

Yeah, it's somewhat baffling and a complete blindside if you're not already familiar with omega-K, but is also a nice introduction to the canon… the weirdness builds gradually but at a nice pace, e.g. with the age (and then seniority) of the test subjects climbing ever higher…

I like this but I ruined the reveal for myself before reading the whole thing because of that flashing text. Beyond the fact that it's super annoying, I was drawn to click it before reading the rest of the article and then saw the link to the end of death thing, so I knew what was going on from the get go. Obviously not your fault, but I really dislike that flashing text.

Beyond that though, this is a pretty clever entry into the end of death series. I found some of the wording in the O5 note to be a little awkward (and fairly informal), but I did like the "it's not our job to change it back line". Overall, +1 from me.

I was originally going to downvote due to the similarity to the shard of glass that kills you

I actually talked to CWW shortly after this went up when they pointed out the similarities as well. I uh… kind of forgot that other piece had existed when I wrote this, but luckily the twists are different enough, even if the core concept shares similarities.
